Vulnerability Details

IP Source Route Vulnerability - CVE-2006-2379:

There is a remote code execution vulnerability in the TCP/IP Protocol driver that could allow an attacker who successfully exploited this vulnerability to take complete control of the affected system.

Mitigating Factors for IP Source Route Vulnerability - CVE-2006-2379:

Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed.

Systems are only at risk if IP Source Routing is enabled. IP Source Routing is disabled on Windows XP Service Pack 2 and Windows Server 2003 Service Pack 1 systems.

Enabling the Routing and Remote Access Service will enable IP Source Routing. However, Routing and Remote Access is disabled on any affected operating system version.

Attacks attempting to exploit this vulnerability would most likely result in a denial of service condition. However remote code execution could be possible.

Workarounds for IP Source Route Vulnerability - CVE-2006-2379:

Microsoft has tested the following workarounds. Although these workarounds will not correct the underlying vulnerability, they help block known attack vectors. When a workaround reduces functionality, it is identified in the following section.

Block IP packets containing IP source route options 131 and 137 at the firewall:IP network packets containing IP source route options 131 and 137 could be used to initiate a connection with the affected components. Blocking network packets that meet these criteria at the firewall or at the router will help protect systems that are behind that firewall or router from attempts to exploit this vulnerability. We recommend that you block all unsolicited inbound communication from the Internet. ISA Server 2004 can be used to block the affected types of traffic.

To help protect from network-based attempts to exploit this vulnerability, use a personal firewall, such as theInternet Connection Firewall, which is included with Windows XP and with Windows Server 2003.By default, the Internet Connection Firewall feature in Windows XP and in Windows Server 2003 helps protect your Internet connection by blocking unsolicited incoming traffic. We recommend that you block all unsolicited incoming communication from the Internet. In Windows XP Service Pack 2 this features is called the Windows Firewall.

To enable the Internet Connection Firewall feature by using the Network Setup Wizard, follow these steps:

Click Start, and then click Control Panel.

In the default Category View, click Network and Internet Connections, and then click Setup or change your home or small office network. The Internet Connection Firewall feature is enabled when you select a configuration in the Network Setup Wizard that indicates that your system is connected directly to the Internet.

To configure Internet Connection Firewall manually for a connection, follow these steps:

Click Start, and then click Control Panel.

In the default Category View, click Networking and Internet Connections, and then click Network Connections.

Right-click the connection on which you want to enable Internet Connection Firewall, and then click Properties.

Click the Advanced tab.

Click to select the Protect my computer or network by limiting or preventing access to this computer from the Internet check box, and then click OK.

Note If you want to enable certain programs and services to communicate through the firewall, click Settings on the Advanced tab, and then select the programs, the protocols, and the services that are required.

Disable IP Source RoutingDisabling IP Source Routing will prevent an affected host from processing IP Source related packets that could allow an attacker to execute code. IP Source Routing processing can be disabled by following these steps:Note Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or view the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe.Note We recommend backing up the registry before you edit it.

In Registry Editor, locate the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\

Add the DWORD Value: DisableIPSourceRouting. Set the value to 2. This value disables IP Source Route processing. By default, this key does not exist.

You must restart your system for this change to take effect.

For additional information on Disabling IP Source Routing please read the Additional Protections information listed in the MSDN Article: How to Harden the TCP/IP Stack.

FAQ for IP Source Route Vulnerability - CVE-2006-2379:

Note SMS uses the Microsoft Baseline Security Analyzer, the Microsoft Office Detection Tool, and the Enterprise Update Scanning Tool to provide broad support for security bulletin update detection and deployment. Some software updates may not be detected by these tools. Administrators can use the inventory capabilities of the SMS in these cases to target updates to specific systems. For more information about this procedure, visit the following Web site. Some security updates require administrative rights following a restart of the system. Administrators can use the Elevated Rights Deployment Tool (available in the SMS 2003 Administration Feature Pack and in the SMS 2.0 Administration Feature Pack) to install these updates.
